摘要
传统盐梯度太阳池(以下简称太阳池)利用盐水的显热蓄热,导致太阳池蓄热密度低,太阳池温度的昼夜变化大,并且受提热影响明显,高温及提热不足情况下,容易导致梯度层失去稳定性。石蜡等低温相变蓄热材料应用于太阳池有利于解决上述问题,文中论述了相变蓄热材料添加到太阳池中的研究现状及发展趋势。
The traditional salt gradient solar pond(solar pond)uses the sensible heat storage of brine water,which leads to the low heat storage density,and the temperature of solar pond varies greatly day and night,which is obviously affected by heat extraction.Under the condition of high temperature and insufficient heat extraction,the gradient zone tends to lose stability.Add the low melting point Phase Change Materials(PCMs),such as paraffin wax,to solar pond will be benefit to solve this problem.In this paper,the research progress of added PCMs to solar ponds is discussed.
